Craig I found the same, some of the sites are a bit off when it comes to bulb fitments, I believe some civics do use the other fittings? according to the other philips fitting guide from the site below (hopefully that is correct!). Sorry if I'm wrong
If you go to
http://www.autobulbsonline.co.uk
then just keep in scrolling down (like your looking for the end of the earth, you will then find a link at the bottom to the Philips bulb fitment guide), not sure why it's hidden down there.
